Effect of Organic Nutrient Management on Soil Chemical Properties, Microbial Population and Nutrient Uptake by Plants.

A field experiment was conducted at University of Agricultural Sciences, Bangalore, during kharif, 2016 to study the effect of organic sources of nutrients on soil chemical properties, microbial population and nutrient uptake by plants. The experiment was laid out in a RCBD with seven treatments replicated thrice. A significant increase in the available NPK status of soil after harvest as compared to initial status was observed. The available nitrogen, phosphorous and potassium were significantly higher with FYM at 50 kg N eq. ha^-1 + vermicompost at 50 kg N eq. ha^-1 + EBDLM at 50 kg N eq. ha^-1 + panchagavya spray (3 %) at 15 and 45 DAS + vermiwash spray at 30 DAS (381.93, 37.67 and 275.73 kg ha^-1, respectively) as compared to other treatments. The same treatment also recorded significantly higher population of bacteria, fungi and actinomycetes (85.37, 13.57 and 14.07 × 10³ CFU g^-1 soil, respectively). The nutrient uptake was also higher in the same treatment. [ABSTRACT FROM AUTHOR]
